Auxiliary contacts 1NO+1NC 5A/250V, HAx disconnectors size 1-4, 20-160A HZC311

Hager auxiliary contacts for disconnectors – reliable circuit status indication

Hager HZC311 series auxiliary contacts are a key element for expanding the functionality of HAx disconnectors. They enable circuit status indication, which is particularly important in automation, control and monitoring systems. This allows both installers and end-users to be sure that the circuit is working correctly and to quickly locate potential problems if necessary.

Mounting and connections

Side mounting of these contacts ensures convenient and quick installation in Hager disconnectors of size 1-4 and rated current 20-160A. The use of screw connections guarantees a secure and durable electrical connection, minimizing the risk of errors and failures. This solution will be appreciated by installers who value solid workmanship and ease of installation.

Functionality and parameters

The set includes both a normally open (1NO) and a normally closed (1NC) contact, providing flexibility in configuring the signaling system. These contacts are characterized by a rated operating current of 6A for AC-15 at 230V, ensuring their reliable operation in typical applications. The lack of fault signaling contacts simplifies the design and focuses on the basic signaling function. Top mounting simplifies access to the contacts during inspection and maintenance.
